Lithium Recycling In The Blanket

Lithium in the breeding blanket is not destroyed by breeding tritium; it can be recovered and recycled, keeping the input demand small.

Lithium is transformed, then recoverable

When blanket lithium absorbs a neutron and breeds tritium, the lithium atom is consumed in that specific reaction, but the surrounding lithium inventory remains and can be reprocessed. Blanket materials are managed so that lithium is recovered, re-enriched if needed, and returned to service rather than discarded after a single pass.

Why recycling keeps demand low

Because the lithium is recovered rather than consumed wholesale, the standing inventory turns over slowly and the makeup demand is small. This keeps the fuel cycle's only mined input modest and reinforces that lithium does not reintroduce a large extractive footprint.

• Only the atoms that breed tritium are consumed
• The bulk lithium inventory is recovered and reused
• Re-enrichment can restore the desired isotope balance
• Makeup demand stays small relative to lithium production

A closed material loop

Lithium recycling turns the blanket into a largely closed material loop, consistent with the sustainability goals of the overall cycle. See lithium for breeding and blanket tritium recovery.

Slow turnover, small makeup

Because only the specific atoms that breed tritium are consumed, the bulk lithium inventory turns over slowly and can be recovered and re-enriched rather than discarded. That keeps the makeup demand small and turns the blanket into a nearly closed material loop. Recycling is what ensures the cycle's single mined input never grows into a significant extractive footprint over a plant's life.
